Consequences | The Flash "Wrath of Savitar" Review

The first clip from the upcoming Flash and Supergirl musical crossover for The Flash is out, and they're literally singing about the power of super friendship.

In season 1, Barry's mentor Harrison Wells aka Eobard Thawne was revealed to be Reverse Flash, who killed the Scarlet Speedster'mother.

On the last episode of The Flash, Barry dealt with the feelings of guilt over how his actions had hurt everyone around him. During the "Arrow", "The Flash", "Supergirl" and "Legends of Tomorrow" panel at PaleyFest, Todd and Aaron's fellow executive producer Andrew Kreisberg revealed that Season 4's big bad will not be another speedster. "They're at the same place, essentially, so they can go on this journey together to get back the love they think they lost or not".

The third season of Flash has been notorious and with Speed Force shaking things up for Barry all the time, full points to the scripting and direction of the show.

Fans have been speculating around the clock about Savitar's identity, and the consensus seems to be that Savitar is one of three characters: H.R., Cisco, or Barry from the future. However, just like Kara, Barry will end up trapped in an alternate world that appears to be a movie a musical and their only way to survive is by singing and dancing.

We're not going to lie to you, you've got to suspend a lot of disbelief to make this episode work, but once you do it's going to be the funnest 45 minutes of your life. Unfortunately, the Music Meister has the power to put people, and in this case, even Supergirl, in a coma. Later in season 2, audience shockingly found that Earth 2's speedster, Jay Garrick/ Hunter Zolomon, was the man behind the black Mask aka Zoom.

When TV Line spoke to the cast of the popular series to find out about the mysterious character of the series, Danielle Panabaker said, "Slowly, different characters are going to learn who Savitar is".

One of the fan theories suggest that Savitar could be the Future Flash pointing out where Savitar tells Team Flash, "I am the future, Flash". ". I nearly don't want to say it, because I don't want to jinx it, but I want to come back".

"The Flash" starring Grant Gustin as Barry Allen / Flash, Carlos Valdes as Cisco Ramon and Candice Patton as Iris West will have a new episode titled "Duet", which is actually a musical crossover episode with "Supergirl".
